[0002] In the construction field, large turnover materials are construction materials that can be reused, circulated among various construction sites, and are relatively large in size. For example, formwork for pouring concrete, steel pipes for scaffolding, rail sleepers for track transportation, safety nets and guardrails for construction safety, etc. These materials play an important role in building construction, can be reused multiple times, and transfer their value while still maintaining their inherent form. Therefore, in project construction, these materials are usually circulated to effectively utilize the turnover materials rationally, optimize resource allocation, reduce construction waste, and save construction costs.

[0003] Currently, when managing large turnover materials, an artificial method is adopted to count the number of large turnover materials at each project construction site and their locations, and then display them in the form of an Excel spreadsheet. When there are quantity changes, manual modification is also carried out. This not only has low efficiency but also makes it impossible for personnel to intuitively understand the quantity situation of large turnover materials at each project construction site, which is very inconvenient for the management of large turnover materials.

[0043] Figure 2 It is a schematic diagram of the overall structure of a positioning and monitoring system for large-scale reusable materials provided by the present invention. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0044] As Figure 1-2 shown, the present invention provides a positioning and monitoring method and system for large-scale reusable materials. Among them, the method and the system complement each other, and the system is used to implement the method. Both are based on the same inventive concept.

[0045] A positioning and monitoring method for large-scale reusable materials includes the following steps:

[0046] Step 1: Obtain the positions of each construction site to obtain the regional coordinates of each construction site;

[0047] Step 2: Obtain the quantity of large-scale reusable materials at each construction site and store the quantity of large-scale reusable materials in a data form;

[0048] Step 3: Establish a blank screen, set a number of pixel points on the blank screen, and the position distribution of each pixel point is represented by pixel coordinates;

[0049] Step 4: Convert the regional coordinates of each construction site into the pixel coordinates to obtain the areas of each construction area on the blank screen;

[0050] Step 5: Convert the quantity of large turnover materials at each construction site into color values through a conversion coefficient, and assign the color values corresponding to each construction site to the areas on the corresponding blank screen.

[0051] In the present invention, through the way of coordinate transformation, the construction areas are transformed onto the screen, and the quantity of large materials is displayed through color values. The larger the color value, the greater the brightness of the displayed color, that is, the lighter the color. The positions of the construction sites are displayed in the monitoring map in the form of areas, and at the same time, the quantity of large turnover materials at each construction site is displayed through the depth of the color, so as to manage the large turnover materials in a visual way, which is clear and intuitive.

[0052] In step 1, obtaining the positions of each construction site to obtain the area coordinates of each construction site includes:

[0053] According to the area shapes of each construction site, intercept the coordinates of each corner vertex within the area shape;

[0054] Connect the coordinates of each corner vertex and check them against the area shape of the construction site to correct the coordinates of the corner vertex;

[0055] According to the corrected coordinates of the corner vertices and in combination with the area shape of the construction site, obtain the coordinate set of the area shape of the construction site as the area coordinates of the construction site.

[0056] In the present invention, according to the area description in the project introduction, the area shapes of each construction site can be obtained, or they can be directly obtained from the map. However, if directly obtained from the map, accurate longitude and latitude need to be used. If obtained from the project introduction, the area coordinates can be customized as long as the coordinate systems of each project are kept consistent. At this time, a two-dimensional coordinate system is used. The area coordinates of each construction site are a coordinate set, including the boundary coordinates and internal coordinates of the area.

[0057] In step 2, obtain the quantity of large turnover materials at each construction site and store the quantity of large turnover materials in a data manner.

[0058] In the present invention, storage in a data manner can use a text format or a database format, and only the corresponding data needs to be called.

[0059] Among them, the methods for obtaining the quantities of large-scale reusable materials at each construction site include one or more of the following: statistical methods and image processing methods; and, the image processing method, as a verification method, can correct the statistical method. When there are multiple methods for obtaining the quantities of large-scale reusable materials at each construction site, after obtaining the quantities of the large-scale reusable materials through the statistical method, the quantities of the large-scale reusable materials are corrected through the image processing method.

[0060] For the statistical method, it can be counted manually or the data can be directly called.

[0061] For the image processing method, the method steps used include:

[0062] Obtain the stacking image of the large-scale reusable materials;

[0063] According to the shape of the large-scale reusable materials, combined with the stacking image, extract the cross-sectional image of the large-scale reusable materials from the stacking image;

[0064] According to the extracted cross-sectional image of the large-scale reusable materials, obtain the quantity of the large-scale reusable materials.

[0065] In the present invention, the stacking image is an image of all the large-scale reusable materials stacked together, and the cross-sectional image is the image of each large-scale reusable material in the stacking image. The cross-sectional images are repetitive in the stacking image. For every large-scale reusable material, there will be one corresponding cross-sectional image in the stacking image. For the extraction of the cross-sectional images, the contour extraction method can be adopted. The same contours are defined as the same cross-sectional images. The image processing method can quickly and accurately obtain the quantity of the large-scale reusable materials, and only one photo of the stacking image is required, which is very easy to obtain in practice.

[0066] For the above-mentioned image processing method, the step of extracting the cross-sectional image of the large-scale reusable materials from the stacking image according to the shape of the large-scale reusable materials and combining the stacking image includes:

[0067] Extract the repetitive images in the stacking image;

[0068] According to the repetitive images, compare the repetitive images with each view of the large-scale reusable materials;

[0069] Take the repetitive images with consistent comparison results as the cross-sectional images of the large-scale reusable materials.

[0070] In the present invention, in order to further accurately count the number of large reusable materials and eliminate the influence of some impurities on the statistics of the quantity of large reusable materials, various views of the large reusable materials are introduced. Each view is compared with the repeated images that protrude. If the comparison is consistent, it indicates that the repeated image is the view of the large reusable material, thereby determining the quantity of the large reusable material and excluding other impurities mixed in the materials stacked in the effective area.

[0071] In step 3, a blank screen is established, and a number of pixel points are set on the blank screen. The position distribution of each pixel point is represented by pixel coordinates.

[0072] The blank screen is used to subsequently draw and display the areas of each construction site, and the color values of the areas of each construction site are displayed, laying a foundation for subsequent visual display. In the present invention, each pixel point corresponds to a pixel coordinate respectively, and thus a matrix will be formed.

[0073] In step 4, converting the area coordinates of each construction site into the pixel coordinates to obtain the areas of each construction area on the blank screen. This process can be refined into the following steps, including:

[0074] Converting the area coordinates of each construction site into the pixel coordinates;

[0075] Marking the name of the construction site on the pixel coordinates corresponding to the converted construction site;

[0076] Showing the marked pixel coordinates on the blank screen to obtain the areas of each construction area on the blank screen.

[0077] In the present invention, through conversion of the area coordinates of the construction site, each construction site is represented on the blank screen, and the coordinates of each construction area are displayed on the blank screen. Compared with the display on the map, the present invention only focuses on the large reusable materials in the construction area, enabling the management personnel to clearly see the positions and quantities of each large reusable material. If the management personnel need to transfer the large reusable materials, they only need to set the color values in such a way that the color values corresponding to the large reusable materials at each construction site are similar and can be visually displayed, facilitating the management of the management personnel. The coordinate conversion only needs to be carried out according to the data relationship between the two coordinates.

[0078] In step 5, the quantity of the large reusable materials at each construction site is converted into color values through a conversion coefficient, and the color values corresponding to each construction site are assigned to the areas on the corresponding blank screen.

[0079] Among them, the quantity of large-scale reusable materials at each construction site is converted into color values through a conversion coefficient. Similar to the above coordinate conversion, it is converted through the conversion coefficient, forming a corresponding relationship between the quantity and the color value.

[0080] Among them, the conversion coefficient is set according to the maximum quantity of the large-scale reusable materials. The maximum quantity of large-scale reusable materials is set by the management personnel based on engineering experience. Generally, for different types of large-scale reusable materials, their corresponding maximum quantities are different.

[0081] Among them, assigning the color values corresponding to each construction site to the areas on the corresponding blank screen includes:

[0082] Obtaining the pixel coordinates of the area of the construction site on the blank screen according to the area of the construction site on the corresponding blank screen;

[0083] Assigning the color values to the pixel coordinates of the area of the construction site on the blank screen in a traversal manner, and modifying its color value to the color value corresponding to the construction site.

[0084] In the present invention, for coloring the color values, in order to display evenly, a method of traversing and coloring each pixel coordinate is adopted, and the color values are set respectively, so as to assign the color values corresponding to each construction site to the areas on the corresponding blank screen, and then complete the visual display, making it clear at a glance for management personnel and leadership personnel when viewing.

[0085] At the same time, for the convenience of management, the quantity of large-scale reusable materials arriving at each construction site will also be displayed on the area of the construction site on the blank screen, so as to complete the quantitative display.

[0086] It should be noted that the quantity of large-scale reusable materials is updated regularly. Therefore, the visual display of the present invention is also updated regularly.

[0087] Based on the above-mentioned positioning and monitoring method of large-scale reusable materials, in order to implement the above method, the present invention also proposes a positioning and monitoring system for large-scale reusable materials, including:

[0088] A construction area coordinate module, used to obtain the positions of each construction site and obtain the area coordinates of each construction site;

[0089] A reusable material quantity module, used to obtain the quantity of large-scale reusable materials at each construction site and store the quantity of large-scale reusable materials in a data manner;

[0090] A screen pixel coordinate module, which is used to create a blank screen, set a number of pixel points on the blank screen, and the position distribution of each pixel point is represented by pixel coordinates;

[0091] A construction area screen module, which is used to convert the area coordinates of each construction site into the pixel coordinates to obtain the areas of each construction site on the blank screen;

[0092] A visualization display module, which is used to convert the quantity of large turnover materials at each construction site into color values through a conversion coefficient, and assign the color values corresponding to each construction site to the areas on the corresponding blank screen.

[0093] The above several modules respectively execute the content of the above method, so as to obtain a visual display of large turnover materials, which is convenient for management and scheduling.

[0094] The above is only a preferred embodiment of the present invention, and does not impose any limitation on the present invention. Any simple modification, change, and equivalent structural change made to the above embodiments according to the technical essence of the present invention still fall within the protection scope of the technical solution of the present invention.
